Just for the record. I have retail versions of both Sims 3 and World Adventures. I let both games patch via the launcher, and when I loaded my game, all the content was there... except for Store items I downloaded from here. So I followed coconner's instructions here:

And now my game works perfectly, all patched up, downloads all showing up. Thanks so much for taking the time to post that, coconner. That, and your Awesome Mod guide, have saved me a lot of headaches.
As to the game itself, I haven't played it much yet, but it sure seems to load a lot quicker than it used to, and it runs a bit more smoothly. I haven't tried the in-game purchase option, and don't intend to. I don't have Create-A-World installed.
